Etymology - Toy

I had trouble tracking down the etymology of the word Toy. It is another one that is of uncertain origin. The best I could do was that it can be traced back to the 13th century with a meaning of "amorous playing, sport," and later in the 15th century "piece of fun or entertainment." It seems to have derived from other words such as playtoy and plaything. All signs point to the word being of Dutch origin.
